The Bosch Aerotwin Upgrade AR20U spans 500 mm and offers a frameless configuration for optimal contact.
Frameless wiper blade delivers a modern tensioned beam, calibrated for constant glass contact across multi-radius glass. A resilient metal spine pairs with a premium silicone edge, producing a crystal-clear pass. Its low-drag aero spoiler reduces drag, while slide-in multi-adapter suits 95% of vehicles for hassle-free fitting. The frameless build shrugs off snow and ice, eliminates corrosion points, and hugs modern glass shapes for superior visibility. Drawbacks: higher upfront cost, refill inserts are non-serviceable, plastic adapters may embrittle in severe cold, and clamping force declines slightly on very flat windshields. Rinse with pH-neutral soap every three months and replace every 12–24 months (6–12 months in extreme climates). Experience silent clarity – elevate now.
